TO ALL WHOM IT MAY CONCERN Beit known that I, JOHN FRANKLIN THOMAS, of Adamstown, in the county of Frederick, and State of Maryland, have invented a new and improved Machine for Distributing Guano and other Manures; and I do hereby declare the following to be a full, clear, and exact description of the same, suicient to enable one skilled in the art to which the invention appertains to make use of it, reference being had to the accompanying drawings, which form a part o f this specification, in which- Figure 1 is a botto'm view'of my invention.

Figure 2 is a longitudinal vertical section of the same.

Figure 3 shows a part of the feed-box.

In this invention the escape ofthe fertilizer from the feed-box is adjusted by a' couple of parallel-rule slides, and the agitating-apparatns is thrown into or out of gear` by a novel and simple arrangement.

In the drawings, A A represent the wheels, working on an axle, B, which carries a cam-wheel, C, near its centre. D D are parts of the frame, and E is the feed-box. F represents the agitator, a pole, having pins ff projecting from it and extending from one end of the feed-box to Vthe other. This pole Fis attached by the pins y or ar1ns )"'j"v to the bottom, F', of the feed-box, which slides longitudinally with the pole F, pinsff and f'f',

and bottom, F', thus forming the agitating-apparatus. The bottom, F', is situated slightly below the .feed-box, and independent of it, sliding back and forth in sockets in short beams F" F", attached to the lower edges of the sides of the feed-box. It is composed'of a bar of wood, bearing on its upper surface a metallic plate,the sides of which project slightly beyond the bar, and are turned up, forming raised lips or edges along each side of the whole length of the bottom, F'. v Apertures g gg are cut at suitable distances through these raised edges; and by means ot' these apertures the fertilizer is discharged from the feed-box, falling through funnels G G to the ground. Rods z' t' z' run through these apertures, being attached to the sides of the feed-box at its bottom, and being fixed in position. y

Above the movable bottom, F', thus formed, are two strips H H, running longitudinally with the bottom, F', a little on each side of its centre, and connected together by parallel-ruler joints., An arm, h, operates them, opening or shutting them at pleasure. When shut, they shut off the supply of` guano from the feed-box, nearly or quite closing it. When opened, they admitv the fertilizer to pass freely from the feed-box through the apertures ggg and the fnnnels G Gto the ground. l

The agtating-apparatus heretofore described is operated by a rod, k, which hooks into the movable bottom, F', and extends to the lever K. The latter pivots-at its centre, and works on a friction-wheel, c'.. At its opposite end it has a short post, k", which is provided with a slot, in'to which drops `the arm L, catching and working the leverK by means of a notchin its under surface. The arm L is attached to another arm or lever M, which is pivoted at its forward extremity so as to vibrate laterally, and has two vertical bolts m m in its under side, provided with frietionroller`s, and tting closely to each side of the cam-wheel C. Apertures m' m' m' are provided in the arm M, by means of which the arm L may benttached to it, at different points, so as to regulate the vibrations of the movable bottom, F', of the feed-box.`

N is a rod, hinged to a cross-beam of the frame D D, and passing under the arm L, its rear end resting on the upper side of a shaft, O, which Works ecoentrically upon hinges or bearings o o. IV is a rod firmly fixed to the sha-ft O, by which the latter may be raised or lowered. A loop,p, is provided, to which to attach the rod P, in order to keep the shaft O elevated for any length of time desired. The rod N, it is evident, will be raised or lowered as the shaft O is turned one way or the other, and as it is raised it will throwthe rod L out ofthe slot in the post k", and ,cause the agitator to cease its motion. Instead of the rod-L and arm M, I may prefer to operate the lever K directly by the cam-Wheel C. l

Having described my invention, what I claim as new, and desire to secure by Letters Patent,is

'1. The agitating-apparatus above described, consisting of pole F, pinsfff'f', and movable bottom F', substantially as described. i

2. The combination of the agitating-appara'tus with the rod c, lever K, arm L, arm or lever M, and camwheel O, substantially as herein setforth.

3. The combination of the arm L with the rod N, eccentric-shaft O, and rod P, substantially as herein. shown and described.

To the above spceication of my improvement I have signed my hand, this 29th day of'May, 1867.

JOHN FRANKLIN THOMAS.
